1246. Hakim bin Hizam narrated that the Messenger of Allāh ﷺ said: "Both the buyer and the seller retain the opinion as long as they have not separated. If they spoke the truth and clarified (any defects or conditions), then they would be blessed in their sale, and if they hid something and lied then their sale would be deprived of blessings." (Sahih) And this is a Sahih Hadith. This is how it was reported from Abū Barzah Al-Aslamī, that two men came disputing to him after the sale of a horse, and they were on a ship, so he said: "I did not see the two of you separate, and the Messenger of Allāh ﷺ said: 'The buyer and the seller retain the choice as long as they did not separate.” Some of the people of knowledge, among the people of Al-Kūfah and others, held the view that the separation refers to speech. This is the saying of [Sufyān] Ath-Thawrī. This has been reported from Mālik bin Anas, and it has been reported from Ibn Al-Mubārak that he said: “How could this be refuted?” And the Hadīth about it from the Prophet ﷺ is Ṣaḥīḥ, and it strengthens this view. And the meaning of the saying of the Prophet ﷺ: “Except for the optional sale” is, that (while they are still together) the seller gives the buyer the option to cancel after the conclusion of the sale. If he chooses to agree to the sale, then he does not have the choice to cancel the sale after that, even if they did not separate. This is how Ash-Shāfi‘ī and others explained it. And what strengthens the view of those who said that the separation refers to them parting, (and) it does not refer to speech, is the (following) Hadīth of ‘Abdullāh bin ‘Amr from the Prophet ﷺ.
